ET Rankings API
The Rankings API is an API extension opened for beta in May 2015. Its use is to give foreign parties, e.g. clans on TrackBase, an interface where they can gather information which are publicly available on TrackBase. With this API the users can build up their really own Tracker website showcasing information from TrackBase. So, as an example, clan XYZ could show the TB top ten players (tsp) on their homepage.
